[0080] Figures 1 to 3 It is a schematic diagram of the structure of a front cover lock in different states according to an embodiment of the present disclosure.

[0081] like Figures 1 to 3 As shown, when the bonnet lock of the present invention is in use, the bonnet lock can be fixed to the vehicle body to lock the bonnet with the vehicle body. The bonnet lock of the present invention has a double-pull unlocking function, that is, when the handle (not shown in the figure) provided in the driver's compartment of the vehicle is pulled twice, the handle can cause the driving component 400 to operate, and further cause the bonnet lock to be opened. Of course, the bonnet lock in the present invention can also be opened electrically, for example, by triggering a trigger switch and other components provided in the driver's compartment, and then causing the driving component 400 to operate by rotating components such as a drive motor. In addition, the bonnet lock of the present invention can also be provided on the bonnet. The present disclosure is not limited to this.

[0082] Specifically, Figure 1The front cover lock shown is in a fully locked state, where the pawl member 300 is in the first position and holds the bolt member 200 in the first locked position; Figure 2 The front cover lock shown is in a semi-locked state, where the pawl member 300 is in the second position and holds the bolt member 200 in the second locked position; Figure 3 The front cover lock is shown to be in a fully open state, ie, an unlocked state, wherein the pawl component 300 is in the third position, and the bolt component 200 is in the open position.

[0083] In a specific embodiment, the front cover lock of the present disclosure may include components such as a lock housing 100 , a lock tongue component 200 , a pawl component 300 , a driving component 400 , and a pushing assembly 500 .

[0084] Figure 4 It is a schematic structural diagram of a lock housing and a supporting component of a front cover lock according to an embodiment of the present disclosure.

[0085] The lock housing 100 is generally formed as a plate-like structure. When in use, the bonnet lock of the present disclosure can be fixed by fixing the lock housing 100 to the vehicle body. In the present disclosure, the lock housing 100 is formed as a part of the housing of the bonnet lock. For example, the bonnet lock may further include an upper cover (not shown in the figure). The lock housing 100 may be fixed to the upper cover and together form the housing of the bonnet lock.

[0086] The lock housing 100 is provided with a first shaft portion 110 and a second shaft portion 120; preferably, one end of the first shaft portion 110 can be fixed to the lock housing 100, and the other end can be fixed to the upper cover; of course, the other end of the first shaft portion 110 may not be fixed to the upper cover; similarly, one end of the second shaft portion 120 is also fixed to the lock housing 100, and the other end may also be fixed to the upper cover.

[0087] The central axis of the first shaft portion 110 is the first rotation axis, and the axis of the second shaft portion 120 is the second rotation axis. More preferably, the first rotation axis is arranged in parallel with the second rotation axis.

[0088] A support component 130 is disposed on the first shaft portion 110 and the second shaft portion 120. Specifically, the upper end of the first shaft portion 110 is disposed on the support component 130, and is preferably fixedly disposed with the support component 130. At the same time, the support component 130 is provided with a through hole, and at least part of the second shaft portion 120 is located in the through hole of the support component 130, thereby limiting the position of the support component 130 through the second shaft portion 120, so that the support component 130 can be fixedly connected to the lock housing 100.

[0089] Figures 5 to 7 It is a schematic structural diagram of different states of a lock tongue component and a pawl component according to an embodiment of the present disclosure.

[0090] like Figures 5 to 7 As shown in FIG. 1 , the bolt member 200 has a first rotation axis and includes a first locking position, a second locking position and an open position. In other words, the bolt member 200 is rotatably disposed on the first shaft portion 110, and as the bolt member 200 rotates counterclockwise (in degrees C), the bolt member 200 is locked. Figures 5 to 7 direction), the locking tongue component 200 can be in the first locking position, the second locking position and the open position in sequence.

[0091] The first locking position may also be referred to as a fully locked position, and the second locking position may also be referred to as a half-locked position.

[0092] The pawl member 300 has a second rotation axis and has a first position, a second position and a third position. In other words, the pawl member 300 is rotatably disposed on the second shaft portion 120, and the pawl member 300 can be driven to move from the first position to the second position, or can move from the second position to the third position.

[0093] Specifically, in Figure 5 In the state shown, the locking tongue component 200 is located in the first locking position, and the pawl component 300 is in the first position. At this time, a pawl portion of the pawl component 300 can cooperate with a feature of the peripheral surface of the locking tongue component 200 and limit the locking tongue component 200 to the first locking position.

[0094] When the pawl member 300 is driven and rotated counterclockwise, it can move from the first position to the second position. Figure 6 In the state shown, the pawl component 300 is in the second position, at which the pawl component 300 can be disengaged from the bolt component 200 (the bolt component 200 located in the first locking position) to allow the bolt component 200 to rotate counterclockwise to lock the bolt. Figure 6 The first locking position shown moves to the second locking position. Meanwhile, in the second locking position, one claw of the pawl component 300 can cooperate with another feature of the peripheral surface of the bolt component 200 and restrict the bolt component 200 to the second locking position.

[0095] When the lock tongue component 200 is in the second locking position, the pawl component 300 can be further driven to move from the second position to the third position. In the third position, the pawl component 300 can be disengaged from the lock tongue component 200 (the lock tongue component 200 located in the second locking position) to allow the lock tongue component 200 to further rotate counterclockwise to move from the second locking position to the open position; in the open position, the front cover of the vehicle is released.

[0096] Structurally, the pawl component 300 of the present disclosure may include: a first pawl part 310, which is formed as an arm of the pawl component 300, and has a force-bearing surface on the first pawl part 310, and the pushing component 500 can apply a thrust to the force-bearing surface to push the pawl component 300 to rotate; more preferably, a flange part 320 is formed on the first pawl part 310, and a surface of the flange part 320 forms a force-bearing surface, thereby enabling the pawl component 300 to easily cooperate with the pushing component 500 described below to be driven by the pushing component 500.

[0097] Figure 8 is a schematic structural diagram of a first spring according to an embodiment of the present disclosure.

[0098] In the present disclosure, the power for the counterclockwise rotation of the locking tongue component 200 may be provided by the first spring 600 .

[0099] In the present disclosure, the first spring 600 may be a torsion spring, one end of which may be stopped on the locking tongue component 200 , and the other end of which may be stopped on the second shaft portion 120 or the supporting component 130 .

[0100] More preferably, if Figure 8 As shown, the support component 130 may include a spring bracket 131, at least part of which is located in the winding space of the first spring 600, and the contact between the spring bracket 131 and the first spring 600 prevents the first spring 600 from generating excessive radial displacement.

[0101] In a specific embodiment, when the lock tongue component 200 is in the first locking position, the connection between the first spring 600 and the lock tongue component 200 and the connection between the first spring 600 and the second shaft portion 120 are arranged close to each other, and at the same time, the spring bracket 131 is arranged away from the connection between the first spring 600 and the lock tongue component 200 and the connection between the first spring 600 and the second shaft portion 120, thereby, the spring bracket 131 can support the first spring 600 more stably.

[0102] Fig. 9 is a schematic structural diagram of a second spring according to an embodiment of the present disclosure.

[0103] In the present disclosure, when the lock tongue component 200 no longer stops the pawl component 300, for example, the lock tongue component 200 is driven by an external force, that is, during the closing process of the front cover, the lock buckle installed on the front cover will apply an external force to the lock tongue component 200, and the lock tongue component 200 will move from the open position to the second locking position, or further, from the second locking position to the first locking position. At this time, the lock tongue component 200 will no longer continue to stop the pawl component 300, and the pawl component 300 will move from the third position to the second position under the action of the second spring 700, or further, from the second position to the first position.

[0104] More preferably, the second spring 700 may be wound on the second shaft portion 120 , and one end of the second spring 700 is stopped on the pawl member 300 , and the other end of the second spring 700 is stopped on the supporting member 130 .

[0105] Fig.10 It is a schematic structural diagram of a driving component according to an embodiment of the present disclosure.

[0106] In the present disclosure, the driving component 400 is rotatably disposed on the second shaft portion 120, so that the driving component 400 has a second rotation axis. Of course, the driving component 400 may also have a rotation axis different from the second rotation axis.

[0107] More specifically, a through hole is formed in the middle of the driving component 400, and at least a portion of the second shaft portion 120 is located in the through hole of the driving component 400, so that when a rightward pulling force is applied to one end of the driving component 400 (in Fig.10 The driving component 400 can generate counterclockwise rotation.

[0108] The middle portion of the driving component 400 does not refer to the position of the geometric center of the driving component 400 , but refers to the portion between two ends (ie, one end and the other end) of the driving component 400 .

[0109] In a specific embodiment, one end of the driving component 400 can be connected to a driving wire. When the handle is operated, the pulling force can be transmitted through the driving wire and the driving component 400 can be rotated. Thus, the driving component 400 includes an initial position and a driving position. Fig.10 In the state shown, the driving component 400 is in the initial position.

[0110] Moreover, the support member 130 may include a limiting boss 132, which is used to limit the driving member 400 in the driving position. In other words, when the driving member 400 is driven to rotate, the driving member 400 can be limited in position by the limiting boss 132 of the support member 130, so that it cannot rotate further, so as to prevent the pawl member 400 from being in the third position through a single operation, and making the front cover lock of the present disclosure in an open state.

[0111] In a preferred embodiment, the driving component 400 is provided with an extension portion 410, which extends from the plane where the driving component 400 is located along the second rotation axis direction, so that when the support component 130 and the driving component 400 are installed in different planes, the extension portion 410 can cooperate with the limiting boss 132 of the supporting component 130 and be limited in position by the supporting component 130. Preferably, the extension portion 410 can be integrally formed with the driving component 400.

[0112] Fig.11 is a schematic structural diagram of a third spring according to an embodiment of the present disclosure.

[0113] More preferably, the driving component 400 is reset by the reset force provided by the third spring 800. Preferably, the third spring 800 is configured as a torsion spring. Under the action of the reset force of the third spring 800, the driving component 400 can move from the driving position to the initial position. Accordingly, in the process of the driving component 400 moving from the driving position to the initial position, no pulling force is provided to the driving component 400 through the driving cable.

[0114] In the present disclosure, the third spring 800 can be wound on the second shaft portion 120 , and one end thereof can be stopped on the extension portion 410 of the driving component 400 , and the other end thereof can be stopped on the supporting component 130 , thereby enabling the third spring 800 to apply a reset force to the driving component 400 .

[0115] In the present disclosure, the supporting component 130 may further include a blocking portion 133 , and the other end of the second spring 700 and / or the other end of the third spring 800 may be stopped on the blocking portion 133 .

[0116] The driving component 400 drives the pawl component 300 to rotate via the pushing assembly 500 , wherein the pushing assembly 500 is disposed at the other end of the driving component 400 .

[0117] Figure 12 to Figure 14 It is a schematic structural diagram of a pushing assembly according to one embodiment of the present disclosure.

[0118] like Figure 12 to Figure 14As shown, the pushing assembly 500 includes a first pushing component 510 and a second pushing component 520 ; wherein the first pushing component 510 and the second pushing component 520 are both rotatably disposed on the driving component 400 , thereby facilitating the installation of the first pushing component 510 and the second pushing component 520 .

[0119] More preferably, the first pushing component 510 and the second pushing component 520 have the same rotation axis, that is, the first pushing component 510 and the second pushing component 520 can be installed on the driving component 400 using the same shaft component, so that the front cover lock disclosed in the present invention has fewer parts and correspondingly has higher reliability.

[0120] Structurally, the first pushing component 510 and the second pushing component 520 of the present disclosure are both roughly V-shaped, that is, both have two arms.

[0121] The first pushing member 510 includes a first force applying surface 511 , and the first force applying surface 511 may be formed as an end surface of an arm portion of the first pushing member 510 .

[0122] When the pawl member 300 is in the first position, the driving member 400 is in the initial position, the first force applying surface 511 of the first pushing member 510 is in contact with or adjacent to the force receiving surface of the pawl member 300, and when the driving member 400 is driven, the first force applying surface 511 can apply thrust to the force receiving surface.

[0123] That is, when the driving component 400 of the present disclosure rotates for the first time, the driving component 400 moves from the initial position to the driving position, and the pawl component 300 is driven to move from the first position to the second position through the first pushing component 510 .

[0124] At the same time, since the first pushing member 510 can maintain pressure contact with the pawl member 300 during the movement of pushing the pawl member 300, the first pushing member 510 will not generate clockwise or counterclockwise movement (in Fig.10 and disengages from the pawl member 300.

[0125] More preferably, a step portion is formed on an arm portion of the first pushing component 510, and accordingly, the first force-applying surface 511 is formed as a surface of the step portion. At this time, the flange portion 320 of the pawl component 300 can be stuck in the step portion, and accordingly, the clockwise rotation of the first pushing component 510 is also prevented.

[0126] Meanwhile, a limiting component 140 is provided on the lock housing 100; preferably, the limiting component 140 can be integrally formed with the lock housing 100. Accordingly, the first pushing component 510 includes a limiting surface 512, which is used to cooperate with the limiting component 140 and limit the first pushing component 510 to the first pushing position, wherein when the first pushing component 510 is located at the first pushing position and the pawl component 300 is in the first position, the first force-applying surface 511 of the first pushing component 510 can cooperate with (contact or be adjacent to) the force-bearing surface of the pawl component 300. Meanwhile, when the pawl component 300 leaves the first position, for example, when the pawl component 300 is in the second position and the first pushing component 510 is in the first pushing position, the first force-applying surface 511 of the first pushing component 510 is spaced apart from the force-bearing surface of the pawl component 300.

[0127] In the present disclosure, when the driving component 400 leaves the initial position, the first pushing component 510 is separated from the limiting component 140 to allow the first pushing component 510 to move from the first pushing position to the second pushing position, or in other words, the first pushing component 510 is allowed to move from the first pushing position to the second pushing position. The "allowing the first pushing component 510 to move from the first pushing position to the second pushing position" in the present disclosure does not necessarily mean that the first pushing component 510 will definitely move from the first pushing position to the second pushing position, but that the first pushing component 510 can move from the first pushing position to the second pushing position, and whether the first pushing component 510 moves from the first pushing position to the second pushing position depends on the position of the pawl component 300.

[0128] Specifically, when the pawl component 300 is in the first position, the first pushing component 510 will not move from the first pushing position to (rotate to) the second pushing position; that is, when the pawl component 300 is in the first position, the pawl component 300 cooperates with the first pushing component 510 to prevent the first pushing component 510 from moving from the first pushing position to the second pushing position.

[0129] Accordingly, when the pawl member 300 is in the second position, the first pushing member 510 will move to (rotate to) the second pushing position, and in the second pushing position, the second pushing member 520 can push the pawl member 300 to move from the second position to the third position. In other words, when the pawl member 300 is in the second position, since the pawl member 300 is separated from the first pushing member 510, the first pushing member 510 can move from the first pushing position to the second pushing position.

[0130] In the present disclosure, the second pushing component 520 includes a second force-applying surface 521. When the pawl component 300 is located at the second position and the driving component 400 leaves the initial position, the pushing assembly 500 changes position relative to the driving component 400, and the second force-applying surface 521 of the second pushing component 520 contacts the force-bearing surface of the pawl component 300 to apply a thrust to the force-bearing surface.

[0131] Specifically, when the driving component 400 is driven for the second time, the second pushing component 520 pushes the pawl component 300 to move, and at this time, the first pushing component 510 does not contact or transmit with the pawl component 300 .

[0132] In the second pushing position, the first pushing member 510 is arranged at the limiting position of the limit block 420 of the driving member 400; Fig.10 The location shown in .

[0133] Specifically, Fig.10 In the direction shown, when the first pushing component 510 leaves the limiting component 140 and the pawl component 300 is located in the second position, the first pushing component 510 will rotate clockwise and make the first pushing component 510 close to the limiting block 420 of the driving component 400, so that the first pushing component 510 can be stably maintained in the second pushing position.

[0134] In the present disclosure, the first pushing component 510 is provided with a limiting protrusion 513, and the second pushing component 520 includes a first pushing arm 522, which cooperates with the limiting protrusion 513 of the first pushing component 510 to make the first pushing component 510 and the second pushing component 520 tightly attached.

[0135] Specifically, a fourth spring 900 is sleeved on the shaft component, one end of the fourth spring 900 is stopped on the first pushing arm 522, and the other end of the fourth spring 900 is stopped on the driving component 400, for example, on the limit block 420 of the driving component 400. At this time, the other end of the fourth spring 900 and the first pushing component 510 are respectively located on both sides of the limit block 420.

[0136] The second pushing member 520 includes a second pushing arm 523; when the first pushing arm 522 is located at the second pushing position, the second pushing arm 523 can push the pawl member 300. Preferably, the reaction force applied by the pawl member 300 to the second pushing member 520 can make the second pushing member 520 have a tendency to rotate clockwise, and at this time, the first pushing arm 522 of the second pushing member 520 can apply an external force to the limiting protrusion 513, and make the first pushing member 510 also have a tendency to move clockwise, thereby, the first pushing member 510 can be more closely attached to the limiting block 420, and will not be separated from the limiting block 420.

[0137] The portion of the second pushing arm 523 that contacts the pawl member 300 extends out of the first pushing member 510 , that is, the second pushing arm 523 is longer than one arm of the first pushing member 510 , so that during the second drive, only the second pushing arm 523 is used for driving.

[0138] Generally speaking, when the pawl component 300 is located in the first position, the driving component 400 moves from the initial position to the driving position, and the pawl component 300 can be pushed to the second position through the first pushing component 510; when the pawl component 300 is located in the second position, the driving component 400 moves from the initial position to the driving position, and the pawl component 300 is pushed to the third position away from the second position through the second pushing component 520, and when the pawl component 300 is located in the third position, the lock tongue component 200 is released, thereby realizing the double-pull unlocking of the front cover lock.

[0139] The front cover lock of the present disclosure may further include: a lock tongue position switch 150 . When the lock tongue component 200 is in the first locking position, the lock tongue position switch 150 is triggered by the lock tongue component 200 .

[0140] According to another aspect of the present disclosure, a motor vehicle is provided, which includes the aforementioned hood lock.
